We had a customer who was bidding on a job for subassembly for a Defense Department manufacturer. Their bill of materials called for a floating insert in 8286 steel with an OEM part number: KNKDL428JT.
This part is an Alcoa part that would not have been delivered for over 29 weeks – that’s more than half of a year! Not only would these parts take way too long, but they were also very expensive.
Functional Equivalents for Keenserts
- Note: Supplying us with your print is extremely important so that we can determine the internal and external threats, the material in all of the specifications for this key locking insert.
We went to our manufacturer, who was able to provide this part in five weeks with full certifications and a certificate of conformance certifying that it was a functional equivalent to the KNK part.
Why Choose MF Supply for Functional Equivalents?
By providing the functional equivalent, we were able to shorten the delivery time from 29 weeks down to five weeks. We obtained a cost savings of 59%. Our customer won the job. Their work was completed on time. The job was more profitable due to the cost savings. The manufacturer was able to pass those savings on to the end-user, and the job has been a repeater, and it’s been profitable for everyone involved.
If you find yourself in this situation and you’d like to evaluate if a functional equivalent is available for your application, or if you’d like to explore if you can save time and money while maintaining quality by using functional equivalence, our team is here for you!

What is a Helical Inset?
A Helical wire insert is a spring-like precision form wire coil that provides a permanent thread that’s stronger than the parent material. They are also often called a screw thread insert or a Helical insert, but the popular brand name is Heli-Coil, a registered trademark of Emhart Teknologies.
What is a KeyLocking Insert?
A key-locking insert is a solid bushing style insert that is threaded on the inside and the outside with keys on the top. It’s commonly called a Keensert or Keysert, and these are the registered trademark names of Huck Patents and Alcoa Fastening Systems.
Why Would I Use a Helical Insert vs. a Keensert, and Vice Versa?
- Strength: A key-locking insert is much stronger than a helical insert, particularly in high temperature and high torque environments.
- Ease of Install: A key-locking insert is easier to install than a helical wire insert.
- Price: A wire insert is much less expensive than a key-locking insert.
When Would I Use a Keensert?
In a heavy-ware, high vibration, high heat situation when you don’t need to save space and the whole depth is not a key consideration. The key-locking insert is the way to go.
When Would I Use a Helical Insert?
If you need to reduce costs, you’re minimizing space. The Helical wire insert is the way to go. They’re very useful for creating a permanent, strong thread and softer material like aluminum or titanium. And they’re best suited to the lower heat environments.

What is the FDA Authorized Appendix A list under the EUA, and why is it important?
What is the EUA?
The EUA or Emergency Use Authorization is evoked during public health emergencies like COVID-19. Through this authorization, the Food and Drug Administration tries to make sure that the public and the medical field have enough medical devices to manage the crisis. They do this by allowing unapproved medical products or medical products that are approved for one use to be used in a different setting to prevent shortages.
Surgical Masks and Non-NIOSH Respirators Under Appendix A
Appendix A PPE
There are two products in Appendix A: surgical masks and non-NIOSH respirators that are made in China.
This is important because you want to know that the mask you are wearing is effective- especially in a pandemic.
So, the FDA has tested and continues to test certain categories of masks to get them on Appendix A to say they are approved for use in a medical setting.
How Do Products Get Put on the EUA?
Companies who want their product to be listed and certified under the EUA can apply for their products to be tested. There is a specific testing protocol that the FDA, in collaboration with the CDC, uses in order to approve products.
